Description: Cisco UCS fc:ErrStatsHist:signalLosses managed object property
What is cucsFcErrStatsHistSignalLosses?
This is the cumulative loss-of-signal events counter: counts how many times this port's receiver detected no optical or electrical signal at all on the line. On one specific historical error-statistics snapshot for an FC port, this is the lifetime tally, so this almost always means a physically absent link — an unplugged cable, a dead transceiver, or a powered-off device on the other end — rather than a data-quality issue. For example, a signal-loss count of 3 lines up exactly with three occasions a server was powered down for maintenance without first disabling the port.
Examples
